Soldered closed sterling silver-filled jumprings are made of a durable outer layer of sterling silver surrounding a copper-alloy core. These items are 10% sterling silver, making them 1/10 silver filled. Jumprings have additional silver plating for uniformity and are completed with an anti-tarnish coating to preserve the beauty. Jumprings handle like sterling silver. Jumpring size, gauge and inside diameter are approximate.
For optimal results, use nylon jaw pliers or pliers dipped in Tool Magic® heavy-duty rubber coating when working with sterling silver-filled jumprings to prevent scratching or marring.
